SCOTT, 0F WAUKEGAN, ILLINOIS, ASSIGNOR TO ARWELL PRODUCTS COMPANY, OF WATJKEGAN, ILLINOIS, A CORPORATION OF ILLINOIS ENVELOPE AND METHOD OF TREATING FURNITURE Application filed November 8, 1930. Serial No. 494,341.

Furniture, rugs, clothing and similar articles which are in use, in storage or carried in stock are very oftensubjected to deteriorathey become infested with vermin, such as moths, bed bugs, lice, fleas and similar destructive insects which are not only obnoxious but which are extremely destructive, often eating or destroying furniture, rugs, clothing and thelike to such an extent that they become worthless or greatly reduced in value.

To obviate the verminous conditions found in furniture and articles of clothing and the like this invention has been devised for the purpose of providing an improved method and means whereby verminous articles may be conveniently enclosed in a temporary envelope or housing of comparatively inexpensive material with said envelope or housing being of sealed or air-tight construction and containing insecticides so that the articles enclosed by the envelope may be continuously subjected to the eflects of the insecticides to de-verminize the articles without subjecting the person using the device to the effects of the insecticides. The improved method furthermore prevents the distributing of the insecticides to the atmosphere of the room in which the operations are being performed and concentrate the entire strength and effect of the insecticides on the articles enclosed in the envelope for the purpose of de-verminization.

It is an object of this invention to provide an improved envelope for the temporary enclosure of furniture and similar articles whereby the insecticides used for treating are prevented from escaping from the envelope, so that the articles are subjected to the full effect of the insecticides. 7

It is also an object of this invention to provide an improved type of a temporary enclosure means whereby verminous articles of furniture and the like may be enclosed in an air-tight chamber and subjectedto the ef-' It is a further object of this invention to sealed with respect to one another after the articles are enclosed in the envelope to afford an air-tight chamber for the articles so that the full effect of the insecticide may be concentrated on the articles.

It is furthermore an object of this invention to provide an improved method for deverminizing articles of furniture and the like by enclosing the articles together with an insecticide in an air-tight temporary housing constructed of inexpensive material providing a confined air-tight space around the articles and subjecting the same to the full effects of the insecticide to cause a thorough deverminization of the articles, with said housing furthermore serving as a protection of the articles against dirt during the time that they are being subjected to the effects of the insecticide within the temporary housing.

Still another object of the invention is to provide a simplified method of de-verminizing furniture and similar articles in the room where the articles are ordinarily used by providing a temporary envelope or casing constructed of sections which'are adapted to be sealed one to another to enclose" articles and an insecticide so that the verminous articles may be thoroughly treated without necessitating the moving of the articles of furniture or the like to warehouses or similar establishments for de-verminization.

It is an important object of this invention to provide an improved type of envelope and method of treating verminous articles by performed to the efi'ects of the insecticide and furthermore obviating the expense and trouble of moving the articles to Warehouses or deverminizing establishments for treatment.

Other and further important objects of this invention-will-be apparentfrom the'disclosures in the specification arid the'raccompanying drawings.

The invention (in a preferred form) is illustrated in the drawings 'and hereinafter more fully described.

The upper hood section or housing of the envelope is closed on four sides and on the top as clearly illustrated inxFigure-l, while the lower mar- .gins of the four sides (are bent outwardly to provide foot flanges 3 which afford a supporting base for the hood or housing 4. The open bottom of the'hood or housing kis -positioned upon"the' baseplate or sheet 1 to enclose the article of furniture 2 and togetherwith'the sheet '1 aflord a confined treat- .ing chamber for the article.

the hood may be secured to the base sheet 1 leaving one corner open so that a liquid instrap 6 to enclose the article in an air-tight chamber and retain the insecticide within the envelope so that the article of furniture may be subjected to the full strength of the insecticide for any predetermined period of time.

The improved envelope may be constructed of a plurality of sections one or more of which may be provided with adhesive flanges or flaps whereby the sections may be securely fastened together to provide an enclosing chamber for containing articles of verminous furniture or other ver minous articles which are to be treated with an insecticide. The improved method subjects articles of furniture and the like directly to the full effects of insecticides in the rooms in which the furniture is ordinarily kept, thereby obviating the necessity of moving or shipping the furniture to warehouses or other disinfecting and de-verminizing establishments. The cost of cleverminizing furniture or other articles is thereby greatly reduced and the improved envelope affords an air-tight chamber within which the article of furniture may be confined to be subjected to the full effects of the insecticide and as well acts as a protective covering to prevent the articles of furniture or the like from becoming dirty or soiled during the time the same are undergoing treatment. The improved method furthermore affords an arrangement whereby the insecticide is not wasted but is concentrated within the treating chamber and therefore saturates all parts of the article which is being treated within the envelope. The improved arrangement also prevents the fumes resulting from the insecticide from floating around in the room in which the article is stored or is being treated so that the persons performing the method of treatment are not subjected to the eflects of the insecticide.

After an article has been de-verminized by subjectingthe same to the effects of an insecticide within the chamber of the treating envelope, the envelope may be easily removed to release the article. If desired, the envelope may be discarded, or, if preferred, may be reused if the hood portion of the envelope is carefully removed in a manner whereby the flanges or flaps thereof may again be glued or stuck or pasted to the base sheet to enclose another article.

Attention is called to the fact that the envelope may be provided in any desired shape or form to suit t 1e articles of furniture or other devices which are to be enclosed and are to be subjected to the effects of an insecticide to de-verminize the articles.

It will of course be understood that various details of construction may be varied through a wide range without departing from the principles of this invention, and it is therefore not the purpose to limit the patent granted hereon otherwise than necessitatedby the scope ofthe appended claims. 1
